Title: Noise On Roland Jazz Chorus 50
Post by: scottman on July 05, 2010, 07:38:56 PM
I have a 20 + year old Jazz Chorus 50 that has a consistent background noise. I've had it checked by a tech and he couldn't find anything wrong.

Is this noise the norm for the Jazz 50? Is there any processing that could fix this noise issue?

As a newbie I don't know enough to be dangerous so any thoughts would be greatly appreciated.

Hi Scott.
Please describe the noise.
Does it respond to any control? How?
Can you record and post a short sample of it?

The noise is a consistent hiss that doesn't change with control movement. It reminds me of a white noise generated noise. It's there from the moment I turn on the amp until I turn it off. The tech cleaned all the contacts and pots but there was no change. I'm wondering if this is just the technology of the day and that it was something you had to put up with. I'll try and record some and then post it.

Thanks
